I don't see how this is clearer than either of the obvious alternatives:
for m in range(0 , 5):
if m == 2:
continue
#loop body
for m in range(0 , 5):
if m != 2:
#loop body
It's certainly /slightly/ shorter, but the problem is not severe
enough to warrant new syntax, imho.
Also, this uses the `with` keyword in a completely different way from
its existing use, which could be confusing.
Cheers,
Chris
